    my guess is that there is a faulty charcoal canister, control vales or hoses.

    when you replaced the fuel cap and the pressure changed,,this allowed the charcoal canister to release a heavy concentration of fuel vapors into the intake tract,,the 02 sensor and the catalytic converter were not able to compensate for this bleed off.

    your cat and 02 sensors
    may be nearing the end of thier operational life.

    I've heard that aftermarket gas caps can cause problems. Might want to get a factory one.
